Freescale Unveils BPON System-on-Chip

Freescale Semiconductor introduced a system-on-chip (SoC) solution for broadband passive optical networking (B-PON). The device integrates Freescale's e300 core (a PowerPC) processor core design), a B-PON media access controller (MAC), Ethernet MACs, and a clock and data recovery (CDR) unit on the same chip. The device's e300 core operates at 266 MHz and includes a 32KB instruction cache and a 32KB data cache. The processor platform integrates a double data rate (DDR) SDRAM memory controller, three 10/100 Ethernet controllers, dual universal asynchronous receiver/transmitter (DUART), Inter-IC (I2C) bus support, serial peripheral interface (SPI), an interrupt controller, general-purpose input output (GPIO), ATM adaptation layer 5 (AAL5) support, and UTOPIA interfaces. The B-PON interface fully complies with the ITU-T G.983 specification.
